The LAN port filters are defined in a table with the following layout::
The table fields have the following meaning:
K
Idx.
Unique index. This entry is required to enable the filters to be distinguished. The
index may be four characters long and selected as desired.
K
D-st., D-end
Destination port range that is to be filtered. A range of 0 to 0 means that no
destination port is affected by this filter.
K
S-st., S-end
Source port range that is to be filtered. A range of 0 to 0 means that no source port
is affected by this filter.
K
Src-address, Src-netmask
A subnetwork of the local network for which the filter is valid can be entered here.
A source address of 0.0.0.0 means that the filter is applied to all computers. A
network mask of 0.0.0.0 means that the filter is applied to all networks (which also
means all computers).
K
Prot
Protocol that is to be filtered. Possible entries are TCP , UDP , ICMP and all .
The setting all filters out every packet from the specified source network or to the
destination network.
K
Type
Filter type. The possible values are Always-filt., Connect-filt. and Internet-filt.
– Always filter: The packet is discarded.
– Connect filter: The packet is discarded if there is no connection to the remote
station.
– Internet filter: The packet is discarded if its destination can be accessed only via
the default route.
The default filter is entered in the above table. It suppresses the unwanted and cost-
intensive connections in Windows networks on IP. These networks regularly send items
such as DNS queries to the local network, which are routed to the Internet without this
filter.
